T0 @ZZ whom t may concern:

Be it known that I, ISAAC C. GRAY, a citizen of the United States,residing at La Fayette, in the county of Tippecanoe and State ofIndiana., have invented new and useful Improvements in Hinges, of whichthe followino1 is a specifica-tion.

This invention re ates to a hinge and particularly to 'a hinge which isespecially adapted for use in connection with closure members which areto swing in both directions.

The primary object of the invention is to provide an inexpensive hingeof this character which can be more easily applied vand is less likelylto get out of Order than are the hinges now in use and is soconstructed that the hinge will automatically act to restore the closuremember to its norma-l position when the closure member has been opened.

Another object of the invention is to provide the hinge wherein the leaffor connection with the closure member is in the form of a yoke on thearms of which are lugs, which through their engagement with a springpressed bar -carried by the other leaf of the hinge not only normallyprevent casual swinging movement of the closure member, but act aslevers to be acted upon by the bar when moving the closure member to aposition to obstruct the opening in which the closure member is mounted.

A further object of the invention is to so construct the leaf of thehinge which is in the form of a yoke that anti-friction devices may beused in connection with the hinge.

1With these and other objects in view, the invention resides in thenovel combina-- tion and arrangement of parts, which will be hereinafterdescribed and particularly pointed out in the claims.

The preferred embodiment of the invention has been illustrated in theaccompanying drawings, although no restriction is necessarily made tothe precise details of construction therein shown, as changes,alterations, and modifications within the scope of the claims may beresorted to when desired.

In the drawings Figure 1 is a view in side elevation of a portion of adoor way wherein the door is connected with the door frame by a hingeponstructed in accordance with the invenlon.

Fig. 2 is a horizontal section upon an enlarged scale on the line 2-2 ofFig. 1.

Fig. 3 is a section on the line 3 3 of Fig. 2.

Fig. 4 is a perspective View of one of the leaves of the hinge.

Fig. 5 is a similar view of the other leaf of the hinge.

Fig. 6 is a detail perspective view of the spring pressed bar carried byone of the leaves of the hinge.

Fig. 7 is a. detail perspective view of the portion of one vof the hingeleaves showing a modification of the invention.

Like characters of reference denote corresponding parts throi'ighout theseveral views in the drawings.

Referring no-w t0 the drawings in detail the letter A designates a.portion' of a door frame wherein a door B is connected with a frame C bythe hinge which is constructed in accordance with my invention and notonly permits the door B to swing in both directions but automaticallyacts upon the door to restore `the same to normal closed position afterthe door has been opened.

The hinge includes leaf member which comprises a rectangular shapedplate 12 which is retained within a recess in the frame C by screws 13.rIhe plate 12 has formed upon one side thereof a central cylindricalhousing 14 which extends within a mortise in the frame C and iseXteriorly threaded for a portion of its length. Threadedly engaged withthe housing 14: to permit its adjustment thereon is a cap 15 in theclosed end of vwhich is formed a central opening alining with a similaropening 17 inthe plate 12. f y

Extending within the housing 14 through the opening in the cap 15 is abary '18 having formed thereon at one end an enlarged head 19 which isarranged Within the opening 17 in the plate 12 and extends beyond theouter face thereof. The bar 18 is yieldably held against slidingmovement in the housing 1a by a coiled expansion spring 2O which ismounted upon the bar to bear against the head 19 and the closed end ofthe cap 15. The tension of the spring 2O on the bar 18 may be regulatedthrough the adjustment of the cap 15 on the housing 1/1.

Formed on the outer face of the plate 12 and arranged upon oppositesides of the opening 17 are a pair of lugs 21 with each lug providedWith a circular head 22 in which is formed a ball race 23.

The other leaf of the hinge comprises a yoke 24 between the arms 25 and26 of Which extends the door B which is connected With the arms of theyoke by screws 27. The yoke 25 serves as a closure member for a recess29 in the closure B in which are received the circular heads 22 on thelugs 21 on the outer face of the plate 12, said lugs extending Withinslots 32 in the closed end of the yoke which slots extend into the arms25 and 26. Arranged in the race Ways 23 are bearing balls 34 Which areengaged by Webs 33 formed integral with the arms of the yoke 2st and actas braces therefor. A hinge pin 35 passes through suitable openings inthe heads 22 and the Webs 33 and the housing 40 of the yoke and acts asa pintle about which the yoke 24 may turn.

The head 19 on the bar 18 extends into the recess 29 and also through acentral slot 36 in the closed end of the yoke 24e and into the housingof the yoke 40, Fig. 3, and is normally held in Contact With a pair ofprojections or lugs 37 on the arms of the yoke by the spring 20.

rlhrough the provision of the spring pressed bar 18 and the lugs 37 onthe leaves of the hinge it is apparent with reference to the drawingsthat the closure member B is normally held against casual swingingmovement by the bar 18, While when the door has been moved to openposition a lug 37 will act as a lever to be acted vupon by the bar 18for restoring the door to a position in which it will obstruct theopening in which it is mounted.

By virtue of the bar 18 in one leaf or member of the hinge beingprovided with the horizontally-disposed head 19, and the other leaf ormember of the hinge being equipped With lateral lugs 37 in engagementwith the face of said head 19, the head is enabled to exertconsiderableleverage and promptly close the door. It will also be notedthat the disposition of the head 19 in the housing 40 of the door leafor member, and the extension of the pintle 35 through said housing,assure the hinge leaves or Leganes members being strongly retained inproper relative positions for eiiicient action of the springbacked headagainst the lateral lugs 37.

In the modified form of the invention disclosed in Fig. 7 in thedrawingsV the leaf, or yoke 24 is identical in construction with thatdisclosed in the preferred form of the invention with the exception,that in the modified form of the invention lugs 37 are bifurcated andhave mounted in the slots therein rollers 38 Which bear on the head 19`on the bar 18.

From the foregoing description taken in connection With the accompanyingdrawings it is apparent that a hinge for the purpose set forth has beenprovided Which is easy to apply, durable in use, and inexpensive ofmanufacture.

Having thus described the invention, What is claimed as new, is

1. In a hinge, the combination of a member having a horizontally slottedplate, an abutment carried by and spaced from the rear of the plate andforwardly-extending horizontally-disposed lugs, a bar having a headmovable in the slot of the plate and also having a portion guided in thesaid abutment thereof, a spring surrounding the bar and interposedbetween the head and said abutment, a second member having meansreceiving the said lugs of the rstnamed member and superimposed thereonand lateral portions opposed to the face of the head on the bar, and apintle extending through the members and connecting the same together.
